Recycling of old pavements is becoming a widespread technique; in order to preserve the natural resources of aggregates and binder, the materials reclaimed from the damaged layers of the pavements maintained are generally reincorporated in the material for new maintenance layers. However, recycling induces some technical challenges. In the case of ...

Ce texte constitue l'introduction à l'atelier « Boucler les grands cycles biogéochimiques » du colloque agroécologie du 18 Octobre 2013. Il est inspiré des réalisations des Chambres d'agricultures, des instituts techniques, des journées d'échange entre les départements Environnement et Agronomie (EA), Physiologie Animale et Système d'Elevage (PHASE...
The aim of this study was to determine the kinetics of fouling and their influence on the performance of a thermal treatment process used for sanitisation of pig slurry. Two temperatures (55 °C and 80 °C) were investigated. One trial was carried out at 55 °C and 80 °C in which the slurry was not re-circulated and one trial at 80 °C in which 100% or...
Poly(ethylene tereftalate) (PET) is a polymer highly susceptible to the hydrolytic reactions that occur during applications and mainly in thermomechanical processing. These reactions lead to the decrease of molecular weight of the polymer, limiting the recycling number of the material. The reactive extrusion of the PET in presence of chain extender...
